Steps to Reproduce

https://zkfiddle.org/sample/14rd56h/1-Column-Hflex-min-vs-CSS-uppercase 
In our application, every column header is set to transform to uppercase by CSS rule.

But on column with hflex=min, the width is calculated for normal case and after rendering, uppercase text is not visible as a whole. I've created simple ZK fiddle to show that problem.
